Concrete Moisture Testing
in Las Vegas
Know your slab is ready before a single plank goes down.
Excess moisture in concrete is the #1 cause of failed flooring installations. Our certified technicians perform industry-standard moisture testing so you install with confidence — no cupping, no buckling, no costly do-overs.
A slab can look dry
and still destroy your floor.
A slab can look bone dry on the surface while holding damaging moisture underneath. Installing over an untested slab risks the entire project.
A moisture-related failure means tearing out and replacing new flooring at full cost. A test is a fraction of that price.
Technical Testing Methods
We use recognized industry-standard methods, selected to match your slab and flooring type.
Relative Humidity (ASTM F2170)
In-situ probes are placed at the correct depth inside the slab to measure internal relative humidity — the most accurate picture of a slab’s true moisture condition. Essential for modern warranties.
Calcium Chloride (ASTM F1869)
Measures moisture vapor emission rate from the slab surface over a set period (lbs/1,000 sq ft/24 hrs).
Vapor Emission Assessment
Evaluates surface vapor emission to flag slabs that release moisture at rates outside manufacturer limits.
pH / Alkalinity Testing
High surface alkalinity can attack adhesives. We test slab pH so adhesive-based systems bond reliably.

Frequently Asked Questions
01 Why do I need concrete moisture testing before installing floors?
Concrete holds moisture that can rise into new flooring and cause cupping, buckling, adhesive failure, and mold. Testing confirms the slab is within your flooring manufacturer’s limits before installation — protecting both your floor and your warranty.
02 How long does moisture testing take?
It depends on the method. Relative humidity (ASTM F2170) probes and calcium chloride (ASTM F1869) tests require a conditioning period, so results are typically read 24 to 72 hours after the test is set. We’ll give you an exact timeline when we schedule.
03 What is the difference between the RH and calcium chloride tests?
The relative humidity test (ASTM F2170) measures moisture deep inside the slab and is considered the most accurate. The calcium chloride test (ASTM F1869) measures moisture emitting from the slab surface. We select the right method — or both — based on your slab and flooring type.
04 What happens if my slab fails the moisture test?
A failing result isn’t the end of the road. We’ll explain your options, which may include allowing more cure time, applying a moisture mitigation system, or choosing a flooring and adhesive rated for higher moisture. You get clear next steps either way.
05 Do new concrete slabs need to be tested?
Yes — new slabs are especially prone to high moisture because concrete releases water for months as it cures. Testing is essential before installing any moisture-sensitive flooring on a fresh slab.
06 Do you serve Henderson and the rest of the Las Vegas valley?
Yes. We provide concrete moisture testing in Las Vegas, Henderson, Summerlin, North Las Vegas, Boulder City, and throughout Clark County.
07 How much does concrete moisture testing cost?
Pricing depends on the number of tests and the methods required for your slab. Call or text us at (702) 685-8880 or request a quote and we’ll give you a clear price for your project.
